Antlion Modmic 4.0 Omni & Unidirectional Review / Test

Today I am testing some headphone peripherals. The Antlion Mod Mic 4.0's. I will be testing out both the Omni-directional and Uni-directional mics, as well as the Antlion TRRS Y-Splitter, and USB Soundcard.

If you are interested in this microphone, it will set you back $55 on Amazon for a mic with a Mute switch or $50 for a mic without a mute switch.

What's In the Box

  1. Modmic 4.0 (with 3.3m Cable Attached)
  2. (2) Base Mounts to mount to multiple Headsets
  3. Additional 3M Adhesive Pad for Base Mount
  4. Pop Filter
  5. 5 Cable Clips
  6. Instructions
  7. Carrying Case
  8. 1-Year Warranty

Performance / Features

The build quality of the mod mic is nice, but nothing outstanding. It has a standard rubber cable, so you will have to be careful about stepping on it, and general wear and tear. The base mount is plastic, but it has a nice strong magnet so the mic will not fall off your headset. Lastly, the carrying case is very nice and seems to provide ample protection when you're transporting your mic.

The omnidirectional version clearly has an omnidirectional polar pattern, and the unidirectional version has a unidirectional polar pattern. 

The omnidirectional mic has a frequency response of 30Hz to 17.5kHz, and it sounds excellent. The unidirectional mic has a frequency response of 100Hz to 10kHz, and sounds a bit hollow, and like it's missing a lot of frequencies.

Both mics have an operating voltage between 1 and 10 volts so you need at least 1 volt to get the mic to work, and if you go over 10v, you risk damaging the microphone.


  • Omni sounds awesome
  • Uni is great at eliminating background noise
  • Allows adding mic to high quality headphones
  • Nice carrying case


  • Uni missing lots of frequencies


These mics are a great idea. The omnidirectional mic will excel in a situation without lots of background noise in a treated room. The unidirectional mic will excel in a gaming situation where you need to worry about avoiding background noise. I would highly recommend these mics to anyone who has a top of the line set of headphones that do not have a microphone. You can get which ever version fits your situation, and get a great mic.

If you have any additional questions about this mics, leave them in the comments on this site or on the youtube channel, and I will try to reply ASAP.
